Abstract: 1,243,200. Drying dielectric materials. J. W, MANN, and G. F. RUSSELL. 9 Aug., 1968, No. 38077/68. Heading F4G. [Also in Division H5] A process of substantially equalizing unevenly distributed residual moisture in a dielectric material which has been subjected to a primary drying step comprises subjecting the material to the heating effect of a high frequency alternating current field of force, the temperature of the ambient air being maintained between 212‹ and 325‹ F. In the process evaporated moisture is prevented from recondensing on the material. The dielectric material may be a web, wood veneer, paper, paperboard, cloth or fibrous pipe. In the apparatus shown the sheet 1 is carried continuously or intermittently by rollers 12 through an electric field produced by pairs of electrodes 2, 3 connected to a radio frequency generator, in a housing, the temperature of the air being maintained above 212‹ F. by heaters 9 (e.g. steam pipes, electric heaters, infra-red heaters).

Abstract: 1,076,029. Circuits employing magnetic storage elements. SIEMENS A.G. Sept. 18, 1964 [Sept. 19, 1963], No. 38115/64. Heading H3B. [Also in Division H1] In a data store parasitic voltages induced in a read-out conductor by current flow in an adjacent control conductor having a common return conductor are reduced by terminating the control conductor with a short-circuit to the return conductor and terminating the readout conductor with an open circuit to the return conductor. Cancellation of read-out voltages is prevented by providing the conductors in pairs L1, L2, S1, S2, with the control conductors S1 S2 being connected together at the input end to a control voltage source Ua, and with the read-out conductors being connected together at one end and connected to opposite ends of the primary winding of an output transformer U at the output end. The arrangement shown is a thin magnetic film storage device including a film element M. When source Ua energizes the control conductors S1, S2 an equal voltage of opposite polarity is reflected from the short-circuited end so that the voltages induced in both L1 and L2 cancel each other out at the primary of transformer U. During read-out the two voltages Un1 and Un2 of opposite polarity which are propagated in opposite directions reinforce in the transformer winding, Un2 passing from L2 to L1 without reflection.

Abstract: An aluminium alloy, suitable as an anode for primary cells (see Group XXXVI) or cathodic protection, consists of 0.001 to 0.15% of Hg, 1 to 20% of one or more addition elements, namely Zn, Mn, Cu, Ag, Cd, Sn, Au, Sb, Mg, Be, Si, Ca, Ba and Sr. optionally up to 1% of Fe and/or Bi, the balance being Al with any impurities. Preferably Mg is present in the amount 0.1 to 15% wherein the corresponding content of Hg is 1/80 th to 1/120 th of that of Mg.  For preparing an Al-Zn-Hg alloy, Zn or preferably Zn-Al eutectic (containing 5% Al; M.P. 380 DEG  C.) is first dissolved in the mercury, e.g. under pressure and in an inert atmosphere such as argon, and the amalgam obtained is then mixed with the necessary amount of molten Al possibly containing other addition elements, e.g. Cu.  The Hg may be introduced into the molten Zn or Zn-Al alloy from a closed siphon tube containing Hg, one end of which is covered by a thin lid of Zn and/or Al and is dipped into the molten metal or alloy.  The alloy may be hammer-hardened and heated at 300 DEG  C. or 490 DEG  C. and water quenched.  It may form a corrosion-resistant coating for stronger metals or be used for journal-bearings.

Abstract: 1409777 Measuring conductivity ECONOMICS LABORATORY Inc 17 Aug 1973 [23 Aug 1972] 38917/73 Heading G1U [Also in Division G3]  A conductivity sensing device has a pair of electrodes immersed in the medium under test and provides an output representing the conductance of the medium while receiving A.C. power during intermittent bursts. A uni-junction transistor astable multi-vibrator 41 has its output pulses squared and inverted by transistors 47, 60. The resulting negative pulses have a mark-space ratio of approx. 1:100 and are used to trigger the gate of a triac 65. The triac feeds A.C. power from terminals 30, 31 to a bridge comprising resistances 72, 73, 74, 80 and a conductivity cell 75. The bridge output is supplied via the zero setting potentiometer 80 and isolating transformer 78 to an amplifier 18 comprising a Darlington pair 98, 100. Compensation for varying temperature in the cell 75 is provided by a thermistor (not shown) in circuit 108 which provides additional load on the amplifier output if the temperature in the cell rises. The amplifier output operates a Schmitt trigger incorporating uni-junction transistor 132 if the cell conductance deviates from normal. The trigger output operates a 20 second monostable based on capacitor 158 and transistors 160, 162. The monostable output is inverted 189 and drives a triac gate 195 to provide A.C. power to output terminals 200, 205. A lamp 201 connected across the output indicates when power is supplied. The output may drive a recorder or an alarm, or may be used to inject conductive matter into the medium of the test cell. The pulsing of A.C. power to the measuring bridge avoids the polarization of the cell electrodes which results in measurement errors Fig. 2 (not shown).
